    Q. 1 Solution Idea Devices Visibility Consistency Constraints Affordance Keyboard Keyboard design is a good design all the Alphabet and numeric are in different section also the special function key are arranged in top of the keyboard, specially delete button is very good deployed at right top, which cannot be accidentally pressed during any typing. Keyboard has strict constraint i.e if we want to used special character which are on numeric buttons these cannot be activated without pressing the shift button. Or some button on keyboard especially on laptop is only work with pressing “fn” key. Atm machine ATM has good visibility because it have a limited amount of button on his left and right side and only some limited amount of processing screen. ATM has low consistence because there is no similar function to perform. ATM machine have strongly constraint because without the limited amount of action the individual can nothing to do. ATM Machine have no good affordance because naive users have facing a lot of difficulty while using the ATM. Digital watch Digital watch have no good visibility because its screen is not visible in full sun light and in darken area. It is not consistence device because every button has its function, we cannot perform similar task with different button or method. Digital watch has less affordance because its button have no label, so the naïve user can not configure the time or date. Digital camera It has consistence function because every time we press the button the same work will be done against mentioned button. Good constraint because a person cannot capture video except listed format. Also we cannot change function or setting of camera. Less affordance because the new user can used Digital camera with facing some difficulties. Q.2 Solution Idea: [image: pK2ZpIj.png]

    Solution Idea: Answer No.1: How decision support system helps to organization: Helps in Decision Making. Decision support systems (DSS) are interactive software-based systems intended to help managers in decision-making by accessing large volumes of information generated from various related information systems involved in organizational business processes, such as office automation system, transaction processing system, Enhance effectiveness. A second category of advantage that has been widely discussed and examined is improved decision making effectiveness and better decisions. Decision quality and decision making effectiveness are however hard to document and measure. Most researches have examined soft measures like perceived decision quality rather than objective measures. Advocates of building data warehouses identify the possibility of more and better analysis that can improve decision making. Improve interpersonal communication. DSS can improve communication and collaboration among decision makers. In appropriate circumstances, communications- driven and group DSS have had this impact. Model-driven DSS provides a means for sharing facts and assumptions. Data-driven DSS make “one version of the truth” about company operations available to managers and hence can encourage fact-based decision making. Improved data accessibility is often a major motivation for building a data-driven DSS. This advantage has not been adequately demonstrated for most types of DSS. Competitive advantage. Vendors frequently cite this advantage for business intelligence systems, performance management systems, and web-based DSS. Although it is possible to gain a competitive advantage from computerized decision support, this is not a likely outcome. Vendors routinely sell the same product to competitors and even help with the installation. Organizations are most likely to gain this advantage from novel, high risk, enterprise-wide, inward facing decision support systems. Measuring this is and will continue to be difficult. Part-(b) Identify the techniques & DSS model in each of the following example scenario S.NO Scenario Technique DSS MODEL 01 What would happen to sale when you cut down advertising cost 20 % What if analysis Model Driven Model 02 Increase the cost of advertisement until sale reach to $ 2 million Goal Analysis Model Driven Model 03 Find out about this year revenue in compare to previous year Data Mining Data Driven Model 04 Past admission analysis using exploration of data and discovering features and pattern Data Mining Data Driven Model 05 To receive 950 dollars what number of item must be solved at the cost of 10$ Data Mining Model Driven Model 06 What is the prediction on sale of next year Data Mining Data Driven Model Question no 2: Identify the type of information system or related sub system that describe the following scenario 01 Management information system to measure the success of your client with your product service 02 Content Management System used to manage contacts, forecast and generate reports for sale 03 Management information system that maintain the correct amount of inventory and notify when under stockage occur. 04 Management information system that guaranteed that produced or completed material shipped to the consumer complies with the company’s quality standards 05 CUSTOMER RELATIONSHIP MANAGEMENT SYSTEM used to notify the customers about product recommendation based on the previous order 06 Material requirement planning system Tracks the whole conversion process of raw material into the finished goods Part-(b) Three point between project life cycle and software development life cycle (SDLC) PDLC SDLC PDLC is defined as a process that is responsible for bringing to market a new product and generally includes the business units. SDLC on the other hand, is used for developing particular software products. SDLC is primarily aimed at solving a specific software problem that may arise. PDLC Phases Are As Follows Idea generation and screening Research Development Testing Analysis Introduction SDLC Phases Are As Follows Requirements gathering or analyzing user requirements Designing the program Coding the program Documentation and testing of the system The project lifecycle concerns itself more with the planning and user facing aspects such as Plan, Execute, QA, UAT, Go Live! The SDLC involves steps such as develop, build, test, and promote, debugging/fix.

    @zareen said in CS604 Assignment 3 Solution and Discussion: Question No 02 12 Marks Suppose a computer lab comprises of two printers, three scanners, and four ROM writers. There are three programs currently running on some computer. Assume program P1 is currently allocated a printer and two ROM writers and it is waiting for a scanner. Program P2 is allocated a scanner and it is waiting for a printer. Program P3 is allocated two ROM writers, a scanner, and a printer. Draw the corresponding resource allocation graph for these three programs. Also specify if the system is in a deadlocked state or not? [image: fEvrDBH.png] The system is not in deadlock state as it is clear from the above graph it is multi instance and circular weight.
